Nonlinear Damping for Shock Protection of Mems Devices Using Shear Thickening Fluid

Year: 2012

Type: conference-paper

Abstract: This manuscript reports the measurement and analysis of nonlinear viscous damping of MEMS actuators immersed in shear thickening fluids (STFs).The linear second-order system model is modified with a power-law damping term to account for the sheardependent viscosity of the fluid.This model is tested using a torsional microactuator immersed in a STF.At high actuation forces, the vibration velocity amplitude drops sharply.This result reveals the potential to use STFs as adaptive, passive dampers for shock protection of MEMS.To date, this is the only study that uses STFs in the context of dynamic damping for MEMS devices.
